Jac

Jac is a self centred Dickhead who only thinks of himself and not others. He will do his very best to get what he wants but when he doesn’t, he becomes a true cunt. Jac is a lady’s man who doesn’t realise how much bigger his head is to his dick.
Jac usually rhymes with lack aka lack of friends.

Oh he’s such a jac! Only hangs out with the girls he knows he can’t get.

Have you seen jac? He’s probably out with his new “girl” again.

JAC

JAC is an abbreviation for “Just A Comment” - most commonly found on Facebook

If someone posts a message asking “Who’s up to go see a baseball game?” And someone may reply “JAC I love baseball!” The commenter is not indicating that they want to go see the game, but instead is just contributing a comment about their love of the sport instead.
